The discharge ports 15′-1, 15′-2,and 15′-3 have a rectangular shape, which may correspond to the shape ofthe housing 10.

An input unit 17, e.g., a user interface, through which a user's may bereceived may provide along a front of the housing 10. For example, theinput unit 17 may be formed on the front lower end of the housing 10,but as can be appreciated, the position at which the input unit 17 maybe place is not limited to the lower end. For example, it may be formedas part of the front plate 15 of the housing 10. The input unit 17 maybe formed so that a part of the user's input is displayed on theoutside, and the remaining components may be formed in the inner space.

The input unit 17 may receive a user's input for the overall operationof the air management device of the present disclosure. Thus, the usercan input the ON/OFF of the air management device, the temperature ofthe discharged air, the air volume, the wind direction, and a useroperation for the operation of various components described laterthrough the input unit 17. The input unit 17 may comprise a push button,a touch input and/or a display.

The input unit 17 may be implemented in the form of a button or a touchpad. As can be appreciated, the input unit 17 may be implemented in theform of a touch screen on the display. In another embodiment, the inputunit 17 and the display may be integrally implemented. A touch panel maybe formed on the display to receive a manipulation input of a userthrough touch.

The wireless communication may be based on infrared(IR) protocol, near field communication (NFC) protocol, Wi-Fi protocol,Bluetooth protocol, Zigbee protocol, BLE (Bluetooth Low Energy)protocol, telecommunication protocol, e.g., LTE or 5G, and/or otherwireless communication protocol. Alternatively, or in addition thereto,a remote controller may be used to allow a user's manipulation to bereceived through infrared communication.

At least four corners of the housing 10, legs 18 of predetermined heightto allow a lower surface of the bottom plate 11 to be a predetermineddistance from a floor or bottom surface of the living space. Further,the legs 18 may create a space in which air can be sucked into a bottominlet 11′ formed in the bottom plate 11. As can be appreciated,additional legs 18 may be provided based on, e.g., the side-to-sidelength of the housing 10.

The outer surfaces of the side plate 12, the top plate 14, the frontplate 15, the first movable panel or plate 16, and a second movablepanel or plate 16′ of the housing 10 may be made of a material toprovide an aesthetically appealing appearance. The outer surface of thehousing 10 may be formed to have an appearance of a household furniture.For example, the material surface of the housing 10 may have anappearance of a wood material, a varnished finish or coated finish.

The interior of the housing 10 may be divided into three spaces, where afirst partition wall 19 separates the primary air flow space 20 and afirst secondary space 22 and a second partition wall 19′ separates theprimary air flow space 20 and a second secondary space 24. Within theprimary air flow space 20, the air in the livable space is forcedthrough the bottom inlet 11′ to be heat exchanged, and exhausted throughthe first, second and third discharge ports 15′-1, 15′-2, 15′-3 into thelivable space. The first retractable fan or first pop-up fan 200 and thehumidifier 400 may be installed within the first secondary space 22, anda machine room 500 and the second retractable fan or second pop-up fan200′ may be installed in the second secondary space 24. The left andright width of the primary air flow space 20 may be at least two timesgreater than the left and right widths of the first secondary space 22and the second secondary space 24. The left and right width of theprimary air flow space 20 may be dependent upon the number of dischargeports 15′-1, 15′-2, 15′-3, . . . 15′-n to be formed in the front plate15 of the housing 10.

Access to the first and second space 22, 24 may be made through thefirst and second moveable panels 16, 16′. The first and second movablepanels 16, 16′ may be installed on the remaining front of the housing 10not covered by the front plate 15. The first and second movable panels16, 16′ may be configured as slidable access panels or plates. See FIG.38. Alternatively, the first and second movable panels may be configuredto be hinged, similar doors, to open or close the first secondary space22 and the second secondary space 24.

As shown in FIG. 4, a heating, ventilation and air conditioning (HVAC)system 100 may be installed in the primary air flow space 20 and may beconfigured to exchange heat with air drawn through the bottom inlet 11′.Thereafter, the suctioned air may discharge to the first, second, andthird discharge ports 15′-1, 15′-2, 15′-3. A replaceable filter 300 maybe placed at a position corresponding to the bottom inlet 11′. Airpassing through the replaceable filter 300 flows through the air passage102 formed in the primary air flow space 20.

A heat exchanger 104 may be provided in the air flow path 102. The heatexchanger 104 may allow a heat exchange between the air flowing in theair flow path 102 and the working fluid of the heat exchange cycle. Forexample, in the case of a cooling operation, the heat exchanger 104 mayreceive heat from the air and may transfer the heat to the outdoor unitfor discharge to the outside. In the heating operation, the heat may betransferred from the working fluid while the air passes through the heatexchanger 104 to be transferred into the living space. Of course, in theheating operation, the heat may be supplied from a separateconfiguration without using the heat exchanger 104. The working fluiddelivered from the outdoor unit is delivered to the heat exchanger 104through the inlet pipe, and the working fluid passed through the heatexchanger 104 is delivered to the outdoor unit through the outlet pipe.A drain pan 108 may be provided under the heat exchanger 104. The drainpan 108 collects and discharges condensed liquid condensed from the airpassing through the heat exchanger 104.

In order to form the air passage 102, the primary air flow space 20 mayinclude components for guiding the flow of air. There may be an inletguide 110 to face the replaceable filter 300. The inlet guide 110 may beprovided over a region corresponding to the inlet 11′. The inlet guide110 may face most of the region or area of the bottom inlet 11′. Anangled guide surface 110′ may formed in the inlet guide 110 so that airpassing through the inlet 11′ region adjacent to the front end of thehousing 10 may be directed or guided to the back plate 13. The slope ofthe angled guide surface 110′ moves away from the bottom inlet 11′toward the rear plate 13 such that a clearance over the replaceablefilter 300 may increase from the front to the rear of the replaceablefilter 300.

The air inlet guide 110 may extend toward the rear plate 13, and the airinlet guide 110 may extend about ⅔ of the bottom inlet 11′. As such, theair inlet guide 110 may allow majority of the suctioned air to bedelivered to the rear of the air passage 102 inside the housing 10. Thedrain pan 108 and a primary impeller guide 120 may be located over anupper surface of the inlet guide 110, which is opposite of the angledguide surface 110′.

The air passage 102 may include an upper guide 112. The upper guide 112may serve as a ceiling or a top cover of the air flow path 102. Theupper guide 112 extends from the back plate 13 to the primary impellerguide 120. The upper guide 112 has a curved surface to prevent formationof a vortex or air turbulence at the portion that meets or connects tothe rear plate 13. In other words, the back plate 13 and the upper guide112 may not be perpendicular to each other. Further, a portion of theinner surface of the rear plate 13 corresponding to the air flow path102 may be curved. The back plate 13 and the upper guide 112 is to be acontinuous curved surface rather than abrupt coupling joints. Toaccomplish such curved surface, the rear surface of the rear plate 13may be formed to protrude or curve to the outside.

The inlet guide 110 and the upper guide 112 may be made of a heatinsulating material or the surfaces of thereof may be coated with a heatinsulating material. The heat insulating material may prevent a heatexchange with the surroundings. The upper guide 112 may contact theupper end of the heat exchanger 104 and may extend to the primaryimpeller guide 120.

As illustrated in FIGS. 6-8, the primary impeller guide 120 is installedin front of the heat exchanger 104. The primary impeller guide 120 mayguide air to be sucked into the air flow passage 102 and discharged tothe indoor space through the discharge ports 15′-1, 15′-2, 15′-3.Primary impellers 131, 131′ and 131″ with primary impeller blades 130,130′ and 130″ and primary motors 132, 132′ and 132″ may be positionedtherein. By dividing the air flow into, e.g., three paths, the primaryimpeller guide 120 separates the air passing through the heat exchanger104. The primary impeller guide 120 may be made of a thermal insulationmaterial to ensure that the heat-exchanged air passed through the heatexchanger 104 can be delivered to the livable space with minimal heatloss rather than being dissipated inside the housing 10.

A primary impeller frame 122 may be formed of or coated with a thermalinsulation material, and serve as the skeleton of the primary impellerguide 120. The primary impeller frame 122 may have a predeterminedthickness in the front-rear direction, and a plurality of primaryimpeller openings 124, 124′, and 124″ may formed therein. As shown inFIG. 7, the first, second and third primary impellers 131, 131′, 131″may be respectively installed in the first, second, third primaryimpeller openings 124, 124′, and 124″ to allow rotation of the first,second, and third primary impeller blades 130, 130′, 130″. The axialcenters of the primary impellers may be equal distant from each other ormay be different.

The primary impeller openings 124, 124′, and 124″ face the heatexchanger 104 to form the primary impeller inlet 126 for the primaryimpellers. However, only a portion of the primary impeller openings 124,124′, 124″ may be open to serve as the primary impeller outlets 128,corresponding to the discharge ports 15′-1, 15′-2, 15′-3. In otherwords, the primary impeller outlets 128 may be formed at a positioncorresponding to the upper side at primary impeller openings 124, 124′and 124″, corresponding to the positions of the first to third dischargeports 15′-1, 15′-2, and 15′-3 of the front plate 15. Hence, thecross-sectional area of the primary impeller outlets 128 may be smallerthan the cross-sectional area of the primary impeller openings 124, 124′and 124″ or the primary impeller inlets 126. The primary impelleroutlets 128 may be provided at an upper end of the openings 124, 124′and 124″. Alternatively, the primary impeller outlets may be provided atthe middle or lower section of the openings 124, 124′ and 124″ dependingon the position of the first to third discharge ports 15′-1, 15′-2,15′-3.

A branch air flow channel or passage 129, e.g., a duct, a passageway,conduit, tunnel, etc., may be formed in the primary impeller frame 122at one side of an inner surface defining the first primary impelleropening 124 and/or the third primary impeller opening 124″. A portion ofthe air flowing through the first primary impeller opening 124 and/orthe third primary impeller opening 124″ may be diverted to the firstand/or second retractable fans 200, 200′. The branch passage 129 may beopen (e.g., an outlet) on both sides of the impeller frame 122 totransfer the diverted air to the first secondary space 22 and/or thesecond secondary space 24.

As shown in FIG. 7, the primary impellers 131, 131′, and 131″ areinstalled in the first, second and third primary impeller openings 124,124′, and 124″, respectively. The first, second and third primaryimpeller blades 130, 130′, 130″ are rotated by the first, second andthird primary impeller motors 132, 132′, 132″, respectively, to providea driving force for the air flow. The impeller motors 132-132″ may becontrolled by a controller 600 (FIG. 42). In the present embodiment, thecontroller 600 may operate the primary impellers 131-131″ to operatesimultaneously or independently from each other. Although three (3)primary impellers 131-131″ are illustrated, additional impellers may beprovided, e.g., additional primary impellers for each of the primaryimpeller openings and/or additional impellers based on the number ofprimary impeller openings. Further, although the primary impellers mayhave the same size and/or the same cubic feet per minute (CFM) for airflow, different sizes or CFM may be used, and/or the size of primaryimpeller openings may vary. Depending on the location of the primaryimpeller inlet and outlet, an appropriate fan type may be use. In thisembodiment, a turbo fan in which air is drawn in the rotational axisdirection and discharged in the centrifugal direction may be used.

In the present embodiment, three (3) dampers, e.g., louvers 141, 142,143, may be positioned corresponding to the three primary impellers 131,131′, 131″. For example, a first louver 141 may be installed in thefirst discharge port 15′-1, a second louver 142 may be installed at thesecond discharge port 15′-2, and a third louver 143 may be installed atthe third discharge port 15′-3. The louvers 141, 142, 143 may besimultaneously or independently driven by the same driving source or byseparate driving sources, respectively, to open and close the dischargeports 15′-1, 15′-2, 15′-3, and to discharge the air. Further, the degreeof opening of the discharge ports 15′-1, 15′-2, 15′-3 may be same ordifferent. As can be appreciated, the number of dampers may be changedbased on aesthetics of the housing, the number and/or size of theprimary impeller openings, and/or the number or size of primaryimpellers in each primary impeller opening.

Opening or closing the louvers 141, 142, 143 may be performed by louvermotors 141 ‘, 142’, 143′. The output shafts of the louver motors 141 ‘,142’, and 143′ are connected to the rotational axes of the louvers 141,142 and 143 so that the louvers 141, 142 and 143 are rotated when theoutput shafts are rotated. The louver motors 141′, 142′, and 143′ may bedriven and/or controlled by the controller 600 to open or close thedischarge ports 15′-1, 15′-2, 15′-3. The louver motors 141′, 142′, 143′may also adjust the opening angles of the louvers 141, 142, 143.

As shown in FIG. 9, a pair of pivot brackets 145 may be attached orformed on each rear surface of the louvers 141, 142, 143. A pivot axishole 145′ may formed in each pivot bracket 145. An output shaft of eachlouver motor 141′, 142′, 143′ may be coupled to one of the pivot axishole 145′. Although the pivot bracket 145 may have a wedge or triangularshape, other shapes may be used. Further, as can be appreciated, thepair of pivot brackets 145 may not be required to be located along thecentral longitudinal axis of each louvre. Alternatively, or in additionthereto, the louvre may be configured to slide, e.g., up and down, toopen and close the primary impeller outlet 128.

The louvre motors 141′, 142′, and 143′ may be fixed to the installationgroove 150 formed in the primary impeller guide 120 using a motor block146. One side of the motor block 146 coupled to the louvre motors 141′,142′,143′ has a shape based on the exterior contour of the louvre motors141′, 142′, and 143′, and the other side of the motor block 146 isinserted and coupled to the installation groove 150.

Each of the louvers 141, 142, 143 may include the pair of pivot brackets145, each bracket having a pivoting hole 145′. One of the pivoting holeis coupled to a shaft of a corresponding louvre motor 141′, 142′, or143′ and the other pivoting hole is coupled to a slave shaft or pin 147.The motor shaft and the slave shaft 147 form a rotation or pivoting axisfor the louvers 141, 142, and 143. A pair of support pieces 149, fixedto the installation groove 150 of the fan guide 120, supports each endof the slave shaft.

In the illustrated embodiment, the slave shaft may be provided for oneof the pair of pivot brackets 145. However, in certain instances, twoadjacent louvers may share the same slave shaft. As shown in FIG. 8, thesecond and third louvers 142 and 143 each include a slave shaft 147 andpair of support pieces. Instead, the adjacent pivot brackets of thesecond and third louvers may share a single slave pin. Alternatively,the slave shafts 147 may be omitted if the shaft of the drive motors141′, 142′ or 143″ extends all the way across between the pivot holes145′ of the pair of pivot brackets 145.

The particular structure and arrangements of the pivot brackets 145 arenot limited to the present disclosure. In this embodiment, the heatexchanged air is exhausted upwards the louvers 141-143 are opened (FIG.33), where the maximum opened position of the louvers 141-143 beinglimited due to the pivot brackets being located along the centrallongitudinal axis of the louvers. However, a lever or linkage may beprovided between the pivot hole 145′ and the motor and slave shafts toallow the louvers 141-143 to be at least perpendicular to the frontplate 15. In such a configuration, heat exchanged air may be exhaustedperpendicular to the front plate 15. Alternatively, the pivot brackets145 may be provided near the bottom of the louvers 141-143.

The output shafts of the louvre motors 141′, 142′, and 143′ may beoperated by setting the speed and torque of the gears therein. Therotational angles of the louvers 141, 142, and 143 may be set by thedegree of rotation of the output shafts of the louvre motors 141′, 142′,and 143′. The rotational angles of the louvers 141, 142, and 143 may becontrolled based on the user selection or a preset operational setting.

The impellers (impeller blades 130, 130′, 130″ and correspondingimpeller motors 132, 132′, 132″) may all be operated simultaneously orindependently. The impellers may be operated in various combinationsaccording to the operation mode of the air management device.

For example, all louvers 141, 142 and 143 may be opened to discharge theheat-exchanged air to the front of the housing 10 when all the impellersmay be operated. At this time, the heat exchanged air may be preventedfrom being supplied to the branch passage 129, e.g., a secondary flowpath, by closing a first damper 206 (FIG. 10). The first damper 206 isopened or closed by an operation of a damper driving motor, which iscontrolled by the controller 600. Alternatively, only one or two of theimpellers may be turned on with one or two of the respective louversbeing opened, while the first damper 206 is closed to prevent heatexchanged air from being supplied to the branch passage 129.

The suctioned air may be supplied to the additional retractable first orsecond fan 200, 200′ in a state in which at least one of the louvers141, 142, and 143 are closed. For example, when all the louvers 141-143are closed, a primary first impeller 131 (primary first impeller blade130 and primary first impeller motor 132) and the primary third impeller131″(primary third impeller blade 130″ and primary third impeller motor132″) may be turned on and the first damper 206may be opened, thesuctioned air flows through the secondary flow passage 129.Alternatively, the three primary impellers 131, 131′, 131″ may be turnedon with the louvers 141 and 143 closed and the damper 206 and louvers142 opened, the heat exchanged air may be supplied to the secondary flowpassage and also discharged through the middle of the housing 10.

As shown in FIGS. 1 and 2, the discharge units or retractable fan 200 or200′ may be provided on either side of the upper surface of the housing10. The retractable fans 200, 200′ may allow first and secondretractable ducts 234, 234′ (or first and second pop-up ducts) toprotrude from the upper surface of the housing 10 to further dispersethe heat-exchanged air to a wider area.

As illustrated in FIGS. 10-16, the first and second retractable fans200, 200′ may be installed on at least one of the first secondary space22 and/or the second secondary space 24 of the housing 10. Although thedrawings illustrate the first and second retractable fans 200, 200′installed in the first secondary space 22 and the second secondary space24, a detailed description of first retractable fan 200 installed in thefirst secondary space 22 is provided. Based on similar configuration,one of ordinary skill in the art may readily understand the installationof the second retractable fan 200′ in the second secondary space 24.

As shown in FIGS. 10-12, a first inner frame 202 may partition the firstsecondary space 22 to form an first inner space 203 and a first verticalduct 208, which are adjacent to each other and allows installation ofthe first retractable fan200 and the humidifier 400, respectively. Thefirst inner space 203 may be accessed through the first movable panel16, which slides left and right with respect to the housing 10 to openor close the first inner space 203.

A connection duct 204 is installed on the right side of the first innerframe 202. The first connection duct 204 is bent to have a reverse ‘L’shape (or “L” shape on the other side), where the inlet communicateswith the branch passage 129 of the fan guide 120 and the outletcommunicates with the first vertical duct 208. A first connection flowpassage 205 is provided at the inlet of the first connection duct 204,where the first connection flow passage is opened or closed by the firstdamper 206. Although the first connection duct 204 is shown to have abent shape, other shapes and configurations are possible in view of thepresent disclosure and knowledge to one of ordinary skill in the art.

As shown in FIGS. 13-16, the first vertical duct 208 extends in thevertical direction to guide the lifting and lowering of a first liftingbox or lift platform 214 such that the retractable first duct 234 of thefirst retractable fan 200 may move along a predetermined trajectory.When the first retractable fan 200 is raised, a first vertical flow path210 is form inside the first vertical duct 208 between the outlet of thefirst connection duct 204 and an inlet of the retractable first duct234. The vertical duct 208 does not necessarily need to be formed in thefirst inner frame 202 and may be made separately installed in the firstsecondary space 22. The vertical duct 208 extends in the verticaldirection to guide the lifting and lowering of the lifting box 214 to bedescribed below so that the popup duct 234 can be lifted along apredetermined trajectory.

A first lift platform 214 of the retractable first duct 234 mayvertically move inside the vertical duct 208 using a first lift gear 212(e.g., a linear gear) and a second lift gear 232 (a circular gear, e.g.,a pinion) driven by a first lift motor 230. The first lift gear 212 maybe a vertical rack formed from top to bottom of the first vertical duct208. The cross-sectional shape of the first lift platform 214 may be thesame as the cross sectional shape of the first vertical duct 208 exceptfor a first indentation 221. The outer surfaces of the lift platform 214may move in contact with the inner surface of the first vertical duct208.

As shown in FIG. 14, a first support ring 216 of a cylindrical shapepasses through the first lift platform 214 to create a firstcommunication passage 218. A first support base 238 is inserted into thefirst support ring 216 to be rotatably supported therein. The firstcommunication channel 218 allows passage of air from the vertical flowpath 210 to a retractable or pop-up channel 236 of the retractable firstduct 234. The first support ring 216 is rotatably fitted with the firstsupport 238 at the lower end of the retractable first duct 234.

A first impeller support 219 having two beams crossing each other may beprovided inside the communication passage 218. A first secondaryimpeller blade 224 driven by an impeller motor (not shown) may bemounted to the first impeller support to pressurize the air dischargedfrom the first retractable fan 200. The impeller motor may be driven orcontrolled by the controller 600.

A rotary motor housing 220 formed of a ring shape may be providedadjacent to the first support ring 216 of the first lift platform 214and may be configured to receive a rotary motor 226. The firstindentation 221 may be provided on one outer surface of the first liftplatform 214, and as shown in FIG. 14, an elevating motor housing 222may formed at the indentation 221. The outer side surface of the firstlift platform 214 may be optimized to have the largest possible surfaceto contact an inner side surface of the first vertical duct 208.

As shown in FIG. 10, the first secondary impeller blade 224 is installedin the first impeller support 219 of the first lift platform 214. Theoperation of the first secondary impeller blade 224 pressurizes the airin the communication passage 218 to allow the air to be further forcethe air through retractable first channel 236. In other words, the airdrawn into the first connection duct 204 and the first vertical duct 208by the impeller, e.g., the first impeller 131, may be further pressurizeby the first secondary impeller blade 224 for travel through theretractable first channel 236.

A lift motor 230 may be mounted at the elevation motor housing 222 ofthe first lift platform 214. The second lift gear 232 may be installedon an output shaft of the lift motor 230 to engaged with the first liftgear 212. Due to engagement of the second lift gear 232 with the firstlift gear 212, the retractable first duct 324 coupled to the first liftplatform 214 of the retractable fan 200 may ascend above or descendbelow the upper plate 14 of the housing 10 based on the operation of thelift motor 230, which may be controlled or driven by the controller 600.The retractable first duct 234 may be cylindrical as shown in thisembodiment. However, the retractable first duct 234 may have othervarious shapes, e.g., a hexahedron shape.

The retractable first duct 234 forms the retractable first channel 236,which is in communication with the first communication passage 218. Thefirst support base 238 of the retractable first duct is inserted intothe first support ring 216 of the first lift platform 214. The outerdiameter of the first support base 238 may be equal to or slightlysmaller than the inner diameter of the first support ring 216 to allowrotation of the first support base 238 relative to the first supportring 216.

A rotary motor 226 may be mounted to the rotary motor housing 220. Anoutput shaft of the rotary motor 226 has a first rotary gear 228, e.g.,a pinion. A second rotary gear 240, e.g., a rack, may be formed aroundthe outer surface of the first support base 238, which engages with thefirst rotary gear 228. The retractable first duct 234 rotates, e.g.,side-to-side, along a path of the second rotary gear 240 when the firstrotary gear 228 is rotated by the rotary motor 226. The rotary motor 226is driven or controlled by the controller 600.

A plurality of discharge vents 242 may be formed on a section of anouter surface of the retractable first duct 234. To allow forceddischarge of the air flowing through the retractable first channel 236,an area where discharge vents 242 is formed may be less than half theouter surface of the retractable first duct 234. Further, the dischargevents 242 may be formed over an area less than 180 degrees with respectto the center of the retractable first channel 236.

A plurality of first directional blades 244 may be stacked verticallyinside the retractable first channel 236. The directional blades 244 maypivot along a horizontal axis to adjust the vertical direction of theair discharged through the discharge vents 242. The directional blades244, as shown in FIG. 13, may have a semi-circular plate shape, and maybe controlled individually or collectively, either manually orautomatically. If manually, at least one of the directional blades 244may include a tab protruding through the discharge vents 242 for a userto grab and orient the directional blades 244, and if automatically, atleast one of the directional blades 244 may be coupled to a motor drivenor controlled by the controller 600.

The second retractable fan 200′ having same or similar configuration maybe installed in the second secondary space 24. FIG. 30 illustrates asecond lift platform 214′, a second support ring 216′, a secondsecondary impeller blade 224′ and second duct 234′. As can beappreciated, the second retractable fan 200′ may be implanted to havecorresponding first lift gear, communication passage, impeller support,rotary motor housing, indentation, elevation motor housing, rotarymotor, first rotary gear, lift motor, second lift gear, retractablechannel, support base, second rotary gear, discharge vents, directionalblades, etc.

In the described embodiments, the first retractable fan 200 and/or thesecond retractable fan 200′ have a cylindrically shaped towerconfiguration. As can be appreciated, other shapes are possible, e.g.,rectangular pillar shape configuration with discharged vents 242provided on one side, by changing the shape of the retractable firstand/or second ducts 234, 234′. The shape of the ducts may be determinedbased on the desire to further distribute or send the heat-exchanged airto a particular location or locations in a room. As can be appreciated,if other shapes are used, the first and/or second support bases 238,238′ may be maintained to be cylindrical for the rotation of theretractable first and/or second ducts 234, 234′.

In the described embodiment, the discharge vents 242 extend in avertical direction while the directional blades 244 are stackedvertically. As can be appreciated, the discharged vents 242 may extendhorizontally while the directional blades 244 are stacked horizontallyto achieve the same or similar results for distributing the air.

A replaceable filter 300 is provided within a push-in/pull-out drawer ata front center of the housing 10. The replaceable filter 300 isinstalled at the bottom inlet 11′ provided defined by the bottom plate11 and purifies/filters the air passing through the bottom inlet 11′.

As shown in FIG. 3, the bottom inlet 11′ is formed at the bottom plate11 located a bottom of the housing 10 and faces the floor on which thehousing 10 is placed. When the housing 10 is place on the floor of alivable space, the inlet 11′ is not visible to a user. However, the useris able to access the replaceable filter 300 through the front of thehousing 10 by pulling out the housing of the replaceable filter 300provided at an entrance formed in the lower portion of the front plate15. Compare FIGS. 1 and 3. Based on such a configuration, thereplacement of the filter(s) at an end of its life cycle may besimplified.

A filter frame 301, e.g., a drawer frame, forms a skeleton of thereplaceable filter 300. The filter frame 301 has a hexahedral shape, anda plurality of passage openings 302 are formed on the bottom. Eachpassage opening 302 is a path through which air is allowed to pass. Inthe present disclosure, three passage openings 302 are provided having asquare shape in a plan view. The shape and size of each passage openings302 may be based on prevention of a plurality of filters 320, 330, and340 located therein from sagging. A first filter 320, a second filter330, and a third filter 340, are sequentially stacked over each ofpassage opening 302.

A front wall 303 forms a front surface of the filter frame 301. Thefront wall 303 forms a partial outer appearance of the housing 10 whenthe filter frame 301 of the replaceable filter 300 is inserted into thehousing 10. A handle 303′ may be provided at a bottom center of thefront wall 303. A user may grasp the handle 303′ to pull the filterframe through the entrance of the front plate 15 to access thereplaceable filter 300.

A pair of side walls 305 extends rearward from both ends of the frontwall 303 and connects to a back wall 307. The back wall 307 may extendparallel to the front wall 303. A plurality of filter partition walls309 connects to the front wall 303 and the rear wall 307 between thepair of side walls 305 to divide the inside of the housing to create theplurality of passage openings 302.

A seating ledge 311 may extend at a lower end of the side wall 305 andthe filter partition wall 309 to provide a seating surface for the edgeof the first filter 320. Alternatively, or in addition thereto, theseating ledge 311 may be formed along a lower end of the front wall 303and the back wall 307. As can be appreciated, the surface area of theseating ledge 311 may be based on prevention of narrowing the air flowcross sectional area.

Support ribs 313 are formed at upper and lower ends of the rear wall 307to protrude to the rear of the filter frame 301. When the filter frame301 is withdrawn from the entrance of the front place 15 for replacementfilter, the filter frame 301 is supported inside the entrance eventhough the filter frame 301 is retained in the housing 10 by a railassembly 350. The filter frame 301 may be withdrawn all the way toexpose the inside surface of the back wall to create a clearance forwithdrawal of the filters while the support rib 313 or portion thereofis maintained within the entrance of the housing 10.

The plurality of filters, e.g., first filter 320, second filter 330, andthird filter 340 provided over each of the passage opening 302. Thefirst filter 320 is first installed over the passage opening 302. Thefirst filter 320 may serve as a pre-filter to filter, e.g., dust. Aplurality of the filtering cells 322 in a mesh network may form thefirst filter 320 and a storage case 324 may be integrally formed,surround the edge of the meshed filtering cells 322 of the first filter320.

The rectangular walls of the storage case 324 may create a predeterminedstorage space 325. The second filter 330 and a third filter 340 may bestacked inside the storage space 325. Excluding the first filter 320, aheight of the storage case 324 may be higher than a stacked height ofthe second and third filters 330, 340. As shown in FIGS. 18 and 19, suchan arrangement may facilitate one-step removal of the first, second andthird filters 320, 330, 340 housed by the storage case 324 from thepassage opening 302 of the filter frame 301 when the retractable filter300 is withdrawn from the entrance of the front plate 15.

The second filter 330 is installed in the storage space 325, and thethird filer 340 is stacked on top thereof. The second filter 330 has aplanar hexahedron shape corresponding to the shape of the storage space325. A HEPA filter may be used as the second filter 330, and the thirdfilter 340 may be a deodorizing filter of activated carbon components.

In order for the filter frame 301 to be pulled out or pushed in of thehousing 10, a rail assembly 350, e.g., drawer slide set, may be isinstalled on the sides of the filter frame 301 and corresponding innersurfaces of the housing 10. See FIG. 20. The rail assembly 350 includesa first rail 352, a second rail 356 and a third rail 360, each rail 352,356, 360 having guide rails at top and bottom, see e.g., guide rails 354of first rail 352. The first rail 352 is attached to the side of thefilter frame 301 and extends in front-to-rear direction, and the secondrail 356 is attached to the inner surface of the housing. The third rail360 is sandwiched in between the first and second rails 352, 358.

Stop rails 354 a, 354 b of the first rail 352 prevent the second andthird rails 356, 360 from falling out of the first rail 352 when thefilter frame 301 is extended out of or retracted into the housing 10. Aplurality of ball rails 362 are provided at upper and lower ends of thethird rail 360, and a ball bearing 364 is rotatably installed at theball bearing rails 362 to facilitate movement of the second and thirdrails 356, 360. When the filter frame 301 is pulled out, the first rail352 moves with the filter frame 301 and the second and third rails 356,360 slide along the first rail 352 relatively. The first rail 352 comesto a stop by bumping into an one end of the second rail 356 with thestop rail 354 b. When the filter frame 302 is pushed in, the first andthird rails 352, 360 slides rearward until the first rail 352 bumps intothe other end of the second rail 356 with the stop rail 354a, as shownin FIG. 20.

As shown in FIGS. 4 and 21, a cleaner 370 configured to remove dust andforeign matter from the first and/or second filters 320 and 330 may beprovided under the bottom plate 11 of the housing 10. The cleaner 370may be configured to linearly reciprocate along the bottom inlet 11′.The cleaner 370 may be configured to operate similar to a vacuum cleanerhaving a suction motor and may optionally include a dust bin and atleast one cyclone in a cleaner body 371. The cleaner 370 is configuredand/or positioned to prevent obstruction of the bottom inlet 11′. Thisconfiguration allows the air in the living room to flow smoothly thebottom inlet 11′ and then into the air passage 102.

As shown in FIG. 22, the cleaner body 371 forms the appearance andskeleton of the cleaner 370. A surface 372 of the cleaner body 371 facesthe bottom plate 11 and may have a predetermined width in front-to-reardirection which may be at least wider than the width of the bottom inlet11′. A suction opening or port 373 may be provided on the surface 372,which is divided into two by cleaner rail 380 extending therethrough. Inan alternative embodiment, a pair of cleaner rails 380 may be providedon the bottom plate 11 at corresponding edges of the bottom inlet 11′ toprovide a single suction port 373. However, when the size of the cleaner370 increases, the weight may become heavy, so that the size of thecleaner 370 may be reduced by allowing the cleaner rail 380 to cross thesuction port 11′. In addition, when the cleaner suction openings 373 aredivided into a plurality, the flow cross-sectional area of each of thecleaner suction openings 373 may be reduced, and the suction forceleakage due to the sagging of the cleaner 370 may be prevented.

An air outlet 377 is provided at one side of the outer surface of thecleaner body 371. The air outlet 377 may be located at a relativelyremote position from the cleaner suction opening 373 exhaust air isdischarged to the outside after dust or foreign matter is removed fromthe air sucked into the cleaner suction opening 373. In such a case, thedust in the air suction into the cleaner suction opening 373 iscollected in a dust bin inside the cleaner body 371. In an alternativeembodiment, the dust may be collected in the dust tank at a separateposition by connecting the discharge hose to the air outlet 377 withouta dust bin inside the cleaner 370.

The cleaner rail 380 is installed across the bottom inlet 11′ on thebottom surface of the bottom plate 11 to allow the cleaner 370 tolinearly reciprocate along the cleaner rail 380. The cleaner rail 380may have an “I” beam shape, where the flanges at top and bottom engagegrooves from in the cleaner body 371. Further, a linear gear, e.g., arack, may be provided between the flanges at the top and bottom of the“I” beam, and may be provided on both sides of the “I” beam. A motorcoupled to a circular gear, e.g., pinion, may be provided in the cleanerbody 371, where the teeth of the pinion engages with the teeth of therack. Based on the actuation of the motor, the cleaner 370 travels alongthe cleaner rail 380, and a number of passes which the cleaner 370travels across the length of the cleaner rail 380 or across theretractable filter 300, either in entirety or partially, may be based ona predetermined cleaning cycle determined by the controller 600.

As shown in FIGS. 22 and 23, elastic bristles 375 are installed aroundthe edge of the cleaner suction port 373. The elastic bristles 375 mayrub against the surface of the first filter 320 and sweep the dust forentry into the cleaner suction port 373. The elastic bristles 375 may bearranged to form a wall around the cleaner suction opening 373. Althougha single line of elastic bristles 375 is shown in FIG. 22, the elasticbristles 375 may be arranged to have a plurality of lines to minimize oreliminate the leakage of suction force. The density of the elasticbristles 375 around the cleaner suction port 373 allows sufficient sealaround the edge of the cleaner suction port 373 such that the suctionair/force of the cleaner 370 may not leak outside of the cleaner suctionport 373.

The elastic bristles 375 may be made of a material capable of elasticdeflection from 0 degrees at the upper end of the elastic bristles 375,and may have a predetermined diameter and a predetermined length. Theelastic bristles 375 may be made of a synthetic material, e.g., plastic,rubber, resin, etc. As can be appreciated, the elastic bristles 375 maybe also made of a natural or organic material, e.g., hair, ofpredetermined stiffness and capable of prescribed degree of elasticdeflection. If the length of the elastic bristles 375 is too longrelative to the prescribed distance between the first filter 320 and thesurface 372, the middle and bottom end of the elastic bristles 375 maydeform to create gaps between the elastic bristles 375. Such gaps createleakage of air, resulting in reduction of suction force. To prevent suchleakage and deformation rather than deflection, the length of thebristles are preselected based on the distance created between the firstfilter 320 and the surface 372.

Depending on the weight of cleaner 370 and/or stiffness of the cleanerrail 380, sagging of the cleaner rail 380 or wobbling of the cleaner 370on the cleaner rail 380 may occur. However, the elastic bristles 375 mayremain in contact with the surface of the first filter 320 due to theelastic deflection, thereby preventing the leakage of suction force. Forexample, at a location where the cleaner 370 sags due to gravity orwobbles on the cleaner rail 380, the degree of deflection of the elasticbristles 375 may be less, but ends of the elastic bristles 375 remain incontact with the surface of the first filter 320 to prevent loss ofsuction force.

Since the replaceable filter 300 is inside the bottom inlet 11′ of thehousing 10 and the cleaner 370 is on the bottom plate 11 of the housing10, a distance between the bottom surface of the first filter 320 andthe surface 372 of the cleaner body 371 may be greater than a distancebetween a bottom surface of the bottom plate 11 and the surface 372 ofthe cleaner body. To prevent such a difference in distance, a step maybe provided at an edge of the first filter 320 such that the bottomsurface of the first filter 320 may be coplanar with bottom surface ofthe bottom plate 11. Alternatively, a height of the step may be greaterthan a thickness of the bottom plate such that the bottom surface of thefirst filter 320 protrudes closer to the surface 372 of the cleaner 370than the bottom surface of the bottom plate 11.

FIGS. 24-29 illustrates a humidifier 400 installed in the first innerspace 203. The humidifier includes an inlet duct 401 penetrating throughthe first partition wall 19 to communicate with the main air passage102. A portion of the air in the main air passage 102 is delivered tothe air inlet duct 401. A inlet fan 403 having an impeller, e.g.,circular impeller, is coupled to the inlet duct 401 such that the air inthe main air passage 102 is sucked into the air inlet duct 401 when theinlet fan is actuated. Because air flowing into the inlet duct 401 haspassed through the replaceable filter 300 (prior to the air being heatexchanged by the heat exchanger 104), the air delivered to the air inletduct 401 is in a purified/filtered state.

The pressurized air of the inlet fan 403 is directed through a transferduct 405 to a steam generator 407. The steam generator 407 generatessteam by heating the water supplied from a bucket 419, e.g., a liquidstorage tank. The steam generator may include a heater to heat theliquid to generate the steam for the humidifier 400, but water moleculesmay be vaporized using ultrasonic waves. In other words, different meansmay be used for generating the steam in the steam generator 407.

The steam generator 407 includes a first discharge duct 409 to exhausthumified air formed by mixing of the steam generated by the steamgenerator 407 and the air suctioned through the air inlet duct 401. Thefirst discharge duct 409 may be connected to first connection passage205 of the first connection duct 204. See FIG. 10. The humidified airflowing through the first discharge duct 409 may be transferred to thefirst connection duct 204 to flow through the first vertical flow path210, the first communication passage 218, and the retractable firstchannel 236, and then expelled through discharge vents 242 when thefirst retractable fan is raised and activated by the controller 600.

As illustrated in FIGS. 24 and 25, the steam generator 407 may include asecond discharge duct 411 in a direction different or opposite from thatof the first discharge duct 409. As can be appreciated, the seconddischarge duct 411 may not be needed if the second retractable fan 200′is not provided. The second exhaust duct 411 delivers humidified air toa connection duct 413. When the humidified air is exhausted to theconnecting duct 413 through the second discharge duct 411, the mixedhumidified air travels to the second vertical duct 208′ of the secondsecondary space 24 for expelling of humified air by the secondretractable fan 200′. The connecting duct 413 extends through the rearspace 13 s formed between a rear surface of the rear plate 13 and thewall surface. Dampers may be provided at the first discharge duct 409and the second discharge duct 411 to control discharge of humidified airproviding humidity to the living space through the first retractable fan200 and/or second retractable fan 200′.

A bucket seat 415 is installed on a bottom surface of the first innerspace 203 to support the bucket 419 with a reservoir 429 and a tiltingtable 449 provided there between. A humidification pump 417 is installedadjacent to the bucket seat 415 to deliver the water supplied from thebucket 419 to the steam generator 407. The tilting table 449 may allowtilting of the bucket 419 such that an upper end of the bucket 419protrudes outward from the first inner space 203 to facilitateinstallation and removal of the bucket 419 into and from the first innerspace 203. See, e.g., FIG. 38.

As shown in FIG. 27, the bucket seat 415 may include a base 421 formounting of the bucket seat 415 at the bottom of the first inner space203 of the first inner frame 202. A pair of guide columns 423 may beprovided at a rear end (closer to the back plate 13) of the base frame421. A pair of guide rails 425 forming a guide slot 427 is provided in agap formed between the pair of guide columns 423. The guide rails 425may be integrally formed on inner surfaces of the guide column 423facing each other, and a space between the guide rails 425 may form theguide slot 427. The guide rails 425 may have a curved shape of apredetermined radius of curvature.

A reservoir tank 429 may protrude from an upper surface of the base 421and may include a temporary liquid bin 431 inside the reservoir tank 429to temporarily store liquid supplied from the bucket 419. An upper plate433 is installed over the reservoir tank 429 over an upper surface ofthe water storage portion 429 of the base frame 421 and a seal isprovided in a groove formed around an upper opening of the temporaryliquid bin 431 between the reservoir tank and the upper plate 433 toprevent liquid leakage. As can be appreciated, the upper plate 433 maybe integrally formed on the base frame 421.

A pair of holes 435 may be provided through supporting walls 437protruding from the upper plate 433. The pair of holes 435 forms arotational or pivoting axis for the tilting table 449. The supportingwall 437 further adds rigidity to the upper plate 437 and the tiltingtable 449 to further support a weight of the liquid in the bucket 419.The supporting walls 437 are formed symmetrically on opposite sides of areservoir inlet formed by an opening on the upper plate. Further, avalve protrusion 443 may extend through the reservoir inlet to extendthrough a valve seal of the bucket 419 to allow liquid to flow into thetemporary liquid bin 431 of the reservoir tank 429. As can beappreciated, the pair of holes 435 may be formed at both sides of thereservoir tank 429.

A tilt stopper 439 may extend from an end of the seating wall 437. Thetilt stopper 439 may comprise at least one angled wall having an inclinelowered toward the front end (closer to the first movable panel 16) ofthe reservoir plate 433. The tilt stopper 439 may support the lowersurface of the tilting table 449 when the tilting table 449 is tiltedtoward the front.

A pair of tilt brackets 445 may include shafts 447 protruding, e.g.,inwards, and inserted into the holes 435. The tilt brackets 445 may beconfigured to be attached to the tilting table 449 by, e.g., screws.Because the shafts 447 are rotatable within holes 435 and the tiltbracket is attached to the tilting table 449, the shafts 447 and holes435 function as a tilt or pivot axis for the tilting table 449, and thetilting table 449 is configured to tilt relative to the base 421 from ahorizontal position to a predetermined angled position, where the limitof the predetermined angled position is set by the tilt stopper 439.

The driving force for the tilting the tilting table 449 is transmittedthrough a tilting rack gear 451. As shown in FIG. 28, the tilting rackgear 451 is provided at a rear end of the tilting table 449. The tiltingrack gear 451 is curved to have a predetermined radius of curvature. Thetilting rack gear 451 is configured to interlock with the guide rail 425of the base 421. Rack teeth 453 are formed on an outer surface of thetilting rack gear 451. The rack gear 453 is operated in engagement withan output gear 467. An interlocking channel 455 is provided on bothsides of the tilting rack gear 451. The guide rail 425 of the base 421is positioned in the interlocking channel 455 to guide the movement ofthe tilting rack gear 451.

The tilting table 449 may include a reservoir cover 457 having a watersupply hole 459. A bellows type connection hose protruding from thebucket 419 may be inserted through the water supply hole 459 to thereservoir inlet 441. Upon insertion, the valve protrusion 443 extendsthrough the valve seal provided in the bellow type connection hose toallow liquid in the bucket 419 to flow temporary liquid bin 431 of thereservoir tank 431.

The driving force for the operation of the tilting table 449 is providedby the tilting driving source 461 shown in FIGS. 26 and 29. The tiltingdriving source 461 may be an electric motor. The tilting driving source461 is installed at the rear of the base frame 421. A tilting reducer463 which decelerates and transmits the driving force of the tiltingdriving source 461 is connected to the output shaft of the tiltingdriving source 461. The reducer housing 465 forms the appearance of thetilting reducer 463, and a plurality of gears are installed in thereducer housing 465. The last gear in the gear train of the tiltingreducer 463 is the output gear 467. The output gear 467 is engaged withthe rack gear 453 of the tilting table 449.

A proximity sensor 470 may be place on the front of the housing 10. SeeFIG. 1. The proximity sensor 470 detects an approach of a user whointends to replace or refill the bucket 419. When the user approachesthe proximity sensor 470, the first movable panel 16 slidesautomatically to an open position to reveal the first inner space 203,and the tilting table 9 may be automatically tilted so that the top ofthe bucket 419 protrudes from the first inner space 203. See FIG. 38. Ascan be appreciated, a manual or touch button may be used instead of theproximity sensor 470, or any other means may be used in place of theproximity sensor 470 to recognize a user's intention to replace orrefill the bucket 419.

As shown in FIGS. 30A-30C and 31, the machine room 500 is formed at oneside of the second inner frame 202′. The machine room 500 may comprise aremaining space other the second vertical duct 208′ formed by the secondspace frame 202′. The upper compartment plate 501 form a ceiling of themachine room 500 and may be located at a position which is a firstpredetermined distance from the upper plate 14 of the housing 10. Thelower compartment plate 501′ may form a bottom of the machine room 500and may be located at a position which is a predetermined seconddistance above the bottom plate 11 of the housing 10. A secondconnection duct 204′ forming the second connection passage 205′ to thesecond vertical duct 208′ is provided below the lower compartment plate501. The air flow from the branch air flow passage 129 (provided on theright side) may be controlled by another damper (not shown), similar tothe first damper 206 for the air flow to the first vertical duct 208.Further, the controller 600 is provided in the machine room 500 for easyaccess and service if needed in the future.

A drain pump 502 may be installed on the bottom of the lower compartmentplate 501′. The drain pump 502 may be situated at a lower position thana bottom of the drain pan 108. A connection hose 504, e.g., a pipe or atube, may connect the drain pump with the drain pan 108. Based on thelower position, the connection hose 504 transfers the condensed water tothe drain pump 502 by gravity. The connection hose 504 may penetrate aside surface of the drain pan 108. The bottom surface of the drain pan108 and a corresponding inner surface of the connection hose 504 may bealigned. As can be appreciated, the connection hose 504 may be connectedto penetrate a bottom of the drain pan 108. The drain pan 108 may beinclined such that the bottom surface of the drain pan 108 is tiltedtoward a side connected to the connection hose 504.

The connection hose 504 may be divided into an upper end 505, aconnection section 505′ and a lower end 505″. The upper end 505 isconnected to the drain pan 108 and the lower end 505″ is connected tothe drain pump 502. The lower end 505″ is located at the lowest positionof the connecting hose 504, and a predetermined height difference existsbetween the upper and lower ends 505, 505″. The connection section 505′is provided where the height difference exists between the upper andlower ends 505, 505″.

A discharge hose 506, e.g., a pipe or a tube, is connected to the drainpump 502. The discharge hose 506 serves to transfer the condensed waterpumped through the connection hose 504 and to the outside through thedischarge hose. The discharge hose 506 extends through a hole 13′b ofthe rear plate 13 to the outside. A minimum height H of the dischargehose 506 is at least 400 mm, and a maximum height H of the dischargehose 506 of the hose through a first hole 13′b of the rear plate 13 maybe an uppermost end of the rear plate 13.

The machine room 500 has a gas supply hose 510, e.g., a pipe or a tube,provided through a second hole 13′a of the back plate 13. The gas supplyhose 510 may be used to supply air containing a higher concentration ofoxygen and/or anion (compared to the ambient air) to the air passage102. The supply of higher concentration of oxygen and/or anion maycreate a healthier living environment. The supply hose 510 may penetratethrough the back plate 13, e.g., the second hole 13′a, the second innerspace frame 202′ and the second partition plate 19′ such that the mainair passage 102 may be configured to receive an additional air supplyprovided via an external source, e.g., an oxygen tank and/or an aniongenerator or an air ioniser. Depending on the size, the anion generatormay be provided inside of the main air passage 102 while the oxygen tankis coupled to the gas supply hose 501.

As shown in FIG. 30D, the second inner frame 202′, which is providedinside the second secondary space 24, provides the second inner spacefor the machine room 500, the second vertical duct 208′, the uppercompartment plate 501, and the lower compartment plate 501′. The secondinner frame 202′ includes holes 202′a, 202′b, 202′c, 202′d and 202′ealigning with the power supply hole 26, through hole 29, a first hole13′a, a second hole 13′b, and through hole 13″, respectively. Further,the second inner frame 202′ may include additional holes or openings forthe third hole 13′c and the second connection duct 204′.

As shown in FIGS. 32 and 33 of the air management apparatus or device,ambient air or indoor air is drawn through the bottom inlet 11′ byturning on at least one of the primary impellers 130, 130′, 130″. Theair passes through the replaceable filter 300 for removal of dust,foreign substances, and odors. The air suctioned through the bottominlet 11′ is directed to flows to the rear end of the air passage 102 bythe inlet guide 110. Because of the angled guide surface 11′ of the airinlet guide 110 being inclined upward toward the rear plate 13, i.e.,the space between the angled guide surface 110′ and the replaceablefilter 300 becomes wider toward the rear plate 13, air passing throughthe replaceable filter 300 is mainly guided toward the rear plate 13.

Air flowing to the rear end of the main air flow passage 102 near therear plate 13 is directed to enter the primary impeller openings 124,124′ and 124″ by the operation and suction force of the primaryimpellers 131, 131′ and 131″. Prior to entering the primary impelleropenings 124, 124′, 124″, the air drawn into the main air flow passage102 is heat-exchanged while passing through the heat exchanger 104. Theupper guide 112 guides the air flowing in the air flow path 102 so thatair is transferred or directed to the heat exchanger 104. The upperguide 112 may allow all of the air flowing in the main air flow path 102to pass through the heat exchanger 104 while preventing the air fromflowing over the top of the heat exchanger 104.

Based to the number of primary impeller openings and/or the number ofprimary impellers being driven, the air flow path may be separated. Forexample, if all three primary impellers 131, 131′, 131″ are driven, theheat exchanged air enters corresponding primary impeller openings 124,124′, 124″. The heat exchanged air is drawn through the primary impellerinlet 126 and exhausted to the primary impeller outlet 128. When thelouvers 142, 142, 143 of the corresponding discharge ports 15′-1, 15′-2,15′-3 are opened to be at a predetermined angle, heat exchanged airexhausted through the primary impeller outlet 128 is guided by thelouvers 141, 142, 143 and discharged into the indoor space.

In the present embodiment, the air or heat exchanged air may bedischarged through the discharge ports 15′-1, 15′-2 and 15′-3 based onthe operation of the primary impellers 131, 131′ and 130″. The dischargeof the air through the discharge ports 15′-1, 15′-2, 15′-3 may beindependently set according to whether the specific primary impellers130, 130′, 130″ are turned ON. For example, when only the first primaryimpeller 130 is turned ON while second and third primary impellers131′,131″ are turned OFF, the first louver 141 may be opened at apredetermined to discharge the heat-exchanged air or air is dispersedonly through the first discharge port 15′-1. When only the secondprimary impeller 131′ is turned ON, the second louver 142 may be openedat a predetermined angle to discharge the air, e.g., heat exchanged air,only through the second discharge port 15′-2. Similarly, when only thethird primary impeller 131″ is turned ON, the third louver 143 may beopened at a predetermined angle to disperse the air only through thethird discharge port 15′-3. However, as can be appreciated, theoperation of the primary impellers 131, 131′ and/or 131″ may be combinedto disperse the air through a combination of corresponding dischargeports 15′-1, 15′-2, 15′-3.

Further, the distance of the air dispersed through the discharge port15′-1, 15′-2, 15′-3 may be independently controlled by varying therotational or pivot angle of the louvers 141, 142, 143. As such, the airmanagement or air dispersal may be performed and combined at the frontregion of the housing 10 according to the operation of the primaryimpellers 131, 131′, 131″ and the rotation angles of the louvers 141,142, 143. Referring to an example in which the air management device isoperated in the present embodiment, three users sitting or standing infront of the housing 10 in a position corresponding to each of thedischarge ports 15′-1, 15′-2, 15′-3, the operation of turning OFF and ONand rotational speed of the primary impellers 131, 131′, 131″) and therotation angle of the louvers 141, 142, 143 may be controlled accordingto each user based on individual needs to manage the air. In the exampleshown in FIG. 33, the first damper 206 on the left side andcorresponding damper on the right side may be closed to prevent air,e.g., heat exchanged air, from being diverted to the retractable firstand second fans 200, 200′ through the branch air flow channel, e.g.,129, where air may directed to the retractable first duct or firstpop-up duct 234 and/or retractable second duct or second pop-up duct234′.

The opening and angle adjustment of the louvers 141, 142, and 143 areperformed by driving the louvre motors 141′, 142′, and 143′. The louvers141, 142, 143 are rotated to an angled opened position when pivotbrackets 145 connected to the output shafts of the louver motors 141′,142′, 143′ are rotated. The output shafts of the louver motors 141′,142′, 143′ may be operated by setting a speed and a torque by areduction gear therein. The rotation angles of the louvers 141, 142, and143 may be set by the degree of rotation of the output shafts of thelouver motors 141′, 142′, 143′.

The rotation or pivot angles of the louvers 141, 142, 143 may beselected by the user selecting a corresponding operation mode from aplurality of preset operation modes. Through this operation, air, e.g.,heat exchanged air, discharged through the discharge ports 15′-1, 15′-2,and 15′-3 may be directly delivered to a specific user or indirectly.For example, when the heat-exchanged air is discharged in the forwarddirection of the discharge ports 15′-1, 15′-2, and/or 15′-3, the air maybe directly delivered to the user in front of the housing 10 when therotation angle of the louvers 141, 142, 143 is ninety (90) degrees froma vertical axis. Alternatively, by adjusting the rotation angle of thelouvers 141, 142, 143 to be less than 90 degrees, air discharged fromthe discharge port 15′-1, 15′-2, and/or 15′-3 may be indirectlydispersed to the user. As can be appreciated, the rotation angle louvers141, 142, 143 may not be fixed to a single angle. Instead, the rotationangle may change between two different angles to disperse the air intothe livable space.

As shown in FIGS. 34-35, the retractable first and second fans 200 maybe operated to disperse air further and/or wider than using only thedischarge port 15′-1, 15′-2, 15′-3. The retractable first and/or duct234, 234′ may protrude above the upper surface of the housing 10 androtate to disperse air to a further and/or wider area including a spaceadjacent to the space in which the air management device is installed.For example, if the air management device of the embodiment is used inthe living room, the air coming out through the retractable first and/orsecond fan(s) 200, 200′ may disperse the air to the adjacent kitchen.

In order for air to be discharged or dispersed to the surrounding spacethrough the discharge vents 242 of the retractable first duct 234, airmay be supplied to through the branch air flow passage 129. The firstdamper 206 may be opened to allow the branch air flow passage 129 andthe first connection duct 204 communicate with each other. When at leastone of the first primary impeller 131 or the third primary impeller 131″is turned on, the heat-exchanged air may be discharged through thedischarge vents 242 of at least one of first or second retractable fans200, 200′ protruding above the top surface of the housing 10. Althoughthe second louver 142 of the second discharge port 15′-2 is opened whenthe second primary impeller 131′ is turned on, the second louver 142 maybe closed similar to first louver 141 and third louver 143 and thesecond primary impeller 131′ turned off while at least one of the firstor third primary impeller 131, 131″ turn on such that air is dischargedor dispersed only through the first and second retractable fans 200,200′.

FIG. 34 illustrates the air flow through the first retractable fan 200on the left side of the housing 10. When the first primary impeller 130is driven to be ON and the first damper 206 is opened, the air exchangedin the heat exchanger 104 flows to the branch air flow passage 129. Airflowing into the branch air flow passage 129 passes through the openedfirst damper 206 to the first connection passage 205 of the firstconnection duct 204. The first connection passage 205 is incommunication with the first vertical flow path 210 of the firstvertical duct 208, so that the air passing through the first connectionpassage 205 flows to the first vertical flow path 210.

In order to discharge the air through the discharge vents 242 of thefirst retractable duct 234, the first retractable fan 200 is raisedabove the upper surface of the housing 10. As previously described, theretractable first duct 234 is supported on a first lift platform 214,and when the lift motor 230 is turned ON, the second lift gear 232rotates along the first lift gear 212 to raise the lift platform 214with the retractable first duct 234, as shown in FIG. 35 in thedirection of the arrow A. See also FIGS. 13, 15 and 16.

The first retractable fan 200 may also rotate in the direction of thearrow B shown in FIG. 35. For rotation, the rotary motor 226 installedin the lift platform 214 may be turned ON. When the rotary motor 226 isdriven, the retractable first duct 234 rotates in conjunction with thesecond rotary gear 240 formed on the first support base 238 of theretractable first duct 234 while the first rotary gear 228 rotates. Byrotating the retractable first duct 234 in a protruding state, theheat-exchanged air may be sent to a desired position by the user.

The discharge vents 242 may formed in an area of less than half of theretractable first duct 234 when viewed from the front. Although theretractable first duct 234 may rotate 360 degrees, the rear surface ofthe housing 10 is installed adjacent to the wall of the living space,and the retractable first duct 234 may substantially discharge air overa rotational region of about 180 degrees. For example, when the user isin front of the discharge ports 15′-1, 15′-2, 15′-3, the user may rotatethe first retractable fan 200 such that discharge vents 242 are directedin the user direction to discharge air to the users. In other words, theair may be discharged to a particular by rotating the retractable fan200 such that the discharge vents 242 face the corresponding spacedesired by the user.

Alternatively, the retractable first duct 234 may discharge the airwhile rotating the retractable first duct 234 by continuouslyreciprocating between predetermined angle ranges from side to side.Alternatively, or in addition thereof, the first directional blades 244may adjust air dispersal in a vertical direction as the air exitsthrough discharge vents 242. By adjusting the longitudinal or lateraldirection of air dispersion, the direction of the heat exchanged air maybe adjusted. Further when the air is discharged through the dischargevents 242 of the first retractable duct 234, the first secondaryimpeller blades 224 may be selectively rotated. The rotation of thefirst secondary impeller blades 224 pressurizes the air in the firstcommunication passage 218 to send the air discharged through theretractable first duct 234 farther.

As can be appreciated similar to selective operation of the retractablefirst and/or second fans 200, 200′, the first to third discharge ports15′-1, 15′-2 and 15′-3 may be selectively opened or closed based on theoperation of the first to third primary impellers 131, 131′, 131″. Forexample, when more users are situated in front of the housing 10, airdispersion of heat exchanged air may be manage air on differentconditions and locations at the same time. In FIG. 35, the first andthird louvers 141 and 143 are shown in a closed position, but may beselectively opened to allow air to discharge through them depending onthe number of users or location for air dispersal.

As previously described, the replaceable filter 300 filters the air. Theair delivered to the bottom inlet 11′ passes directly through the firstfilter 320. Since the first filter 320, the second filter 330, and thethird filter 340 are sequentially stacked on the filter frame 301,filtered air further filtered through the second filter 330 and thethird filter 340 to further remove dust, fine dust, and odors areremoved. Thereafter, air passing through the replaceable filter 300enters the main air flow passage 102.

After extended and/or continuous filtering based on the operation of theair management device in the livable space, dust and odor components maybe collected by the replaceable filter 300. The filter cleaner 370 isoperated to maintain the performance of the replaceable filter 300 abovea certain level of performance. The filter cleaner 370 is installed atone side of the bottom surface of the bottom plate 11, which is an areaoutside the bottom inlet 11′, and moves along the cleaner rail 380 uponreceiving an operation signal from the controller 600.

As the filter cleaner 370 passes through the bottom inlet 11′, dust andforeign matter are sucked through the cleaner suction port 373, e.g.,dust and foreign matter in the first filter 320 enter the cleanersuction port 373 by the suction force of the cleaner 370. Based on thefilter cleaner operation, the performance of replaceable filter 300,e.g., the first filter 320, may be improved.

As previously discussed, the filter cleaner 370 has a predeterminedweight and may sag on the cleaner rail 380 due to gravity. For example,the filter cleaner may sag at the middle of the cleaner rail, which maycorrespond to the farthest location from the ends of the cleaner rail380 mounted to the bottom plate 11 of the housing, the elasticdeflection of the elastic bristles 375 around the cleaner suction port373 provide continuous contact with the bottom inlet 11′ to prevent lossof suction force. Even if the distance between the surface of the firstfilter 320 and the filter cleaner 370 changes, the degree of elasticdeflection of the elastic bristles 375 may change to allow continuouscontact between the first filter 320 and the filter cleaner 370. Thefilter cleaner 370 performs the cleaning on the first filter 320 whilelinearly reciprocating along the cleaner rail 380. When the cleaning ofthe first filter 320 is completed, the filter cleaner 370 rest on thebottom surface of the bottom plate 11, e.g., at an end of the cleanerrail 380, to prevent impediment of the bottom inlet 11′.

After extended use or cleaning of the replaceable filter 300 isinsufficient, the first, second and third filters 320, 330, and 340 inthe filter frame 301 may be removed from the housing 10 for replacement.When the user grasps and pulls the handle 303′, the filter frame 301 maybe pulled out of the housing 10 like a drawer. The rail assembly 350 isassists in withdrawal of the filter frame 301 from the front of thehousing 10, as illustrated in in FIG. 36. When the filter frame 301 iswithdrawn from the front of the housing 10, the support rib 313 at therear end of the filter frame 301 is hooked inside the bottom entry forthe filter frame 301 at the bottom of the front plate 15 of the housing10 to support the rear end of the filter frame 301 and to prevent thefront end of filter frame 301 from falling. Further, the rail assembly350 couples the filter frame 301 to the housing 10 to the filter frame301 from falling out arbitrarily.

In this state, the second filter 330 and the third filter 340 in thestorage space 325 are simultaneously removed from the filter frame 301together with the first filter 320 when the storage case 324 is liftedout of the filter frame 301. The filters 320, 330, and 340 in the threepass openings 302 may be all be pulled out to perform maintenance orreplacement. After maintenance or replacement with new filters, thestorage case 324 with filters 320, 330, and 340 may be placed back intothe plurality of passage openings 302 of the filter frame 301. Forexample, the second filter 330 and the third filter 340 are sequentiallystacked in the storage space 325 of the storage case 324 and arepositioned in the passage openings 302, and thereafter, the filter frame301 is pushed or slide back into the housing 10.

Humidification may be added to the air being discharged through thefirst and/or second retractable ducts 234, 234′ in two scenarios. In thefirst scenario, humidification of the air may be possible without theheat exchange through the heat exchanger 104, i.e., humidification andfiltering of the ambient air. In the second scenario, humidification ofthe air may be possible for all heating modes of operation.

In the first scenario, the inlet fan 403 is operated to suck air in fromthe main air flow passage 102 through the inlet duct 401. The airpressurized by the inlet fan 403 is sent to the steam generator 407through the transfer duct 405. In the steam generator 407, the liquidsteam/vapors made by heating the liquid delivered from the bucket 419 ismixed with the air. The humidified air may be delivered through at leastone of the first discharge duct 409 or the second discharge duct 411 toat least one of the first retractable duct 234 or the second retractableduct 234′, respectively.

FIG. 37 illustrates the delivery of the humidified air to theretractable first duct 234 on the left side of the housing 10 by openingthe first discharge duct 409 to the first connection passage 205 of thefirst connection duct 204. The first damper 206 may be closed and thefirst primary impeller 130 may be turned OFF. Optionally, if the heatexchanger is maintained in an OFF state, the first damper 206 may beopened and the first primary impeller 130 may be turned ON to allow anair flow through the branch air flow passage 129. The humidified airfrom the first discharge duct 409 passes through the first connectionpassage 205 and the first vertical flow path 210 to the retractablechannel 236 of the first retractable duct 234. The humidified air isdischarged through the discharge vents 242 of the first retractable fan200 protruding above the upper surface of the housing. The firstretractable duct 234 may be rotated to disperse the humidified air to afarther and wider area. Further, the first secondary impeller blades 224may be driven to pressurize the humidified air to be discharged farther.

In the second scenario, humidification may be additionally performed forduring heating or cooling operation of the HVAC system 100. In such acase, heat exchange is performed in the heat exchanger 104, and theheat-exchanged air is dispersed through at least one of the dischargeports 15′-1, 15′-2, 15′-3. While being discharged therethrough, thehumidified air may be simultaneously discharged through the firstconnection passage 205, the first vertical flow 210, the retractablechannel 236 in order to be discharged into the indoor space, similar tothe first scenario.

As can be appreciated, liquid, e.g., water or mixture with solvent, isrequired for humidification, and may be stored and suppled from thebucket 419. As previously described the bucket 419 is seated on thebucket seat 415 in the first inner space 203. As shown in FIG. 38, whenthe proximity sensor 470 recognizes the user, the first movable panel 16slides to the left side, and the tilting table 449 of the bucket seat415 is operated to be inclined downward toward the front of the housing10. The inclined position of the bucket 219 assists the user to readilyremove and replace the bucket 419 from the first inner space 203. Afterremoval and/or replacement of the bucket 219, the proximity sensor 470operation instigates the return of the tilting table 449 to a horizontalposition, and the first movable panel 16 closes the first inner space203.

FIGS. 39 and 40 illustrates the operation of the tilting table 449. Seealso FIGS. 26-28. When the tilting table 449 is rotated, the tiltingtable 449 is rotated about the shaft 447 with respect to the base 421.The force for the rotation of the tilting table 449 is provided by themotor 461, and the tilting reducer 463 operates the gear train. As theoutput gear 467 of the tilting reducer 463 is rotated in engagement withthe rack teeth 453, the tilting rack gear 451 moves along the guide rail425 of the base 421. Because the guide rail 425 is positioned in theinterlocking channel 455 of the tilting rack gear 451 and guides thetilting rack gear 451 to be moved by the output gear 467, the tiltingtable 449 is rotated about the shaft 447.

As the tilting table 449 rotates about the shaft 447, the tilting table449 may be selectively positioned between the horizontal state and theinclined state. Because the bucket 419 is positioned on the tiltingtable 449, the bucket 419 is in an inclined state when the first movablepanel 16 is opened, and the bucket 419 is in an horizontal state whenthe first movable panel 16 is closed. When the bucket 419 seated on thetilting table 449, the valve in the bucket 419 is opened by the valveprotrusion 443 so that liquid may be delivered to the temporary liquidbin 431. The liquid in the temporary liquid bin 431 may be delivered tothe steam generator 407 by the humidification pump 417 to be heated andvaporized.

When the working fluid and air exchange heat in the heat exchanger 104,moisture in the air may condense and water may form on the surface ofthe heat exchanger (104). As the size or the quantity of the condensateformed on the heat exchanger 104 increases, the condensed water may flowdown the surface of the heat exchanger 104 and collect in the drain pan108, as illustrated in FIG. 41. The condensed water collected in thedrain pan 108 may flow by gravity into the connection hose 504. Whencondensed water is delivered to the drain pump 502 through theconnection hose 504, the drain pump 502 operates to pressurize thecondensed water. The pressurized water is pumped along the interior ofthe discharge hose 506. The condensate flowing along the discharge hose506 may be pressurized and moved up to the maximum height H of thedischarge hose 506. After the condensed water is delivered to themaximum height H of the discharge hose 506, the condensed water may bedischarged by gravity action thereafter.

Because the connection hose 504 has a lower end 505″ connected to thedrain pump 502 and the upper end 505 connected to the drain pan 108 andthe drain pan 108 is inclined toward the connection hose 504, thecondensate collected at the drain pan 108 naturally flows down theconnection hose 504 by gravity and fed to the drain pump 502. Hence, thecondensate on the drain pan 108 is naturally fed by gravity to firstfill the connection hose 504, and after the connection hose 504 isfilled, the drain pan 108 starts collecting the condensate.

After the drain pan 108 has collected a predetermined amount ofcondensate or after a predetermined time period of operating the heatexchanger 104, the drain pump 502 is operated or turned ON. For example,a sensing means may be provided in the drain pan 108 to determine thepredetermined amount of condensate, or a timer may be started by thecontroller to start the operation of the drain pump 502. If thecondensed water stagnates too long in the drain pan 108, there may be ahygiene problem, such as bacteria propagation, and it may beneficial tominimize the time that the condensed water pools in the drain pan 108,the air to the drain pump 502.

In order to minimize suction power and prevent damage to the drain pump502, the operation of the drain pump 502 may be stopped in the statewhere water may remain at the lower end 505″ of the connection hose 504.As shown in FIG. 41, the operation of the drain pump 502 may be stoppedat the water level A indicated by arrow A. The position indicated byarrow A may correspond to the minimum level of condensate inside theconnection hose 504. The highest water level in the connection hose 504may be the upper position of the connection section 505′.

FIG. 42 illustrates a schematic diagram of an air management apparatus,and FIG. 43 illustrates a flowchart of a control method for the airmanagement apparatus. FIGS. 44 and 45 illustrate flowcharts of thecontrol methods according to another embodiments.

As illustrated in FIGS. 42 and 43, the input unit 17 may be configuredto receive a user's manipulation provided on the front surface of thehousing 10. The user may input and set an operation of the airmanagement device through the manipulation of the input unit 17. Theuser may directly touch the input unit 17 or may input the useroperation through a wireless communication with an external device. Upondetermination of a valid user operation through the input unit 17, thecontrol unit 600 starts an operation for air discharge from the airmanagement apparatus. [S101: User Operation Input step].

The controller 600 drives at least one of the primary impeller motors132, 132′ and/or 132″ upon a valid user operation through the input unit17. [S103: Primary Impeller Motor Driving Step]. Upon activation of theprimary impeller motor(s), at least one of the primary impeller blades130, 130′ and/or 130″ of the primary impellers 131, 131′ and 131″installed in the primary impeller guide 120 rotates to create asuctioning force. [S105: Primary Impeller Operation Step]. The airoutside of the air management system is sucked through the bottom inlet11′ and introduced into the primary air flow space 20 therein. [S107:Air Suction Step].

When air flows into the primary air flow space 20 through the bottominlet 11′, heat exchange proceeds in the heat exchanger 104 providedinside the housing 10. To this end, the control unit 600 drives the heatexchanger 104. Specifically, the air passing through the bottom inlet11′ flows through the primary air flow path 102 to exchange heat withthe heat exchanger 104. [S109: Heat Exchange Step]. At least one of theprimary impellers 131, 131′ and/or 131″ continue to operate to suctionthe air in the primary air flow passage 102 through the heat exchanger104 to deliver the heat exchanged air to at least one of the dischargeports 15′-1, 15′-2, and/or 15′-3 provided on the front plate 15 ofhousing . [S111: Air Supply Step to Discharge Port]. In order todischarges the air provided to the at least one discharge ports 15′-1,15′-2 and/or 15′-3 to the outside, the corresponding louvers 141, 142and 143, which are separately driven by louver motors 141′, 142′ and143′, must be opened. [S113: Louver Opening Step].

As previously described, the heat exchanged air may be supplied to theat least one of the first retractable fan 200 through the branch airflow passage 129 in the first primary impeller opening 124 or the secondretractable fan 200′ through another corresponding branch air flowpassage in the third primary impeller opening 124″. For example, thebranch air flow passage 129 may transfer the heat-exchanged air to thefirst retractable fan 200. The first retractable fan 200 allows thepop-up duct 234 to protrude from the upper surface of the housing 10 todisperse the heat exchanged air farther and wider.

If the first or the second retractable fan 200 or 200′ is not used, thecontroller 600 closes the first damper 206 to prevent passage of airthrough the branch air flow passage [S115: Damper Closing Step], and theheat-exchanged air is discharged through at least one of the pluralityof discharge ports 15′-1, 15′-2, 15′-3 with at least one of the louvers141, 142, 143 opened to the front of the housing 10. [S117: AirDischarge Step]. Further, the angle of the louvers 141, 142, 143 may beadjusted by the controller 600 based on the current supplied to thelouver motors 141′, 142′ and 143′.

FIG. 44 in conjunction with FIG. 42 illustrate an additional controlmethod of the air management apparatus for discharging the heatexchanged through at least one of the first retractable fan 200 or thesecond retractable fan 200′ without air discharge through the dischargeports 15′-1, 15′-2 and 15′-3. Steps S201 to S209 of FIG. 44 may be thesame or similar Steps S101 to S109 of FIG. 43, and hence, thedescription is omitted. For purpose of illustration, the followingdescription pertains to discharge of air through the first retractablefan 200.

In Step S211 [S211: Louver Closure Step], the louvers 141, 142, and 143are closed to prevent air from being discharged through the dischargeports 15′-1, 15′-2, and 15′-3. The control unit 600 simultaneously orsequentially opens the first damper 206 to supply air to the firstretractable fan 200 through the branch air flow passage 129. [S213:First Damper Opening Step]. As such, the heat exchanged air is suppliedto the branch air flow path 129. [S215: Branch Air Flow Step].Consequentially, the air through the branch air flow passage129 issupplied to the first retractable fan 200. [S217: Air supply Step forAdditional Discharge]. The first retractable fan 200 protruding aboveone side of the upper surface of the housing 10 discharges the heatexchanged air to the outside. [S219: Air Discharge Step].

FIG. 45 in conjunction with FIG. 42 illustrate an additional controlmethod of the air management apparatus for discharging the heatexchanged through at least one of the first retractable fan 200 or thesecond retractable fan 200′, which may be rotated. For purpose ofillustration, the following description pertains to discharge of airthrough the first retractable fan 200.

A user may input a user operation for lifting and rotating the firstretractable fan 200 through the input unit 17. [S301: User OperationInput Step]. When the user's manipulation according to the operation ofthe first retractable fan 200 is received, the control unit 600 drivesthe lift motor 230 for the first retractable fan 200 to protrude abovethe upper surface of the housing 10. [S303: Lift Motor Driving Step]. Bythe driving of the lift motor 230, the first retractable fan 200 israised to protrude to the upper surface of the housing (10). [S305:Raising of the Fan 200 step].

The controller 600 may drive a motor to rotate the first secondaryimpeller blade 224 to pressurize the air discharged through the firstretractable fan 200. The first secondary impeller blade 224 pressurizesthe air in the first communication passage 218 received through thebranch air flow passage 219 to send the air farther. [S307: RotateSecondary Impeller Blade Step]. The air heat exchanged by the heatexchanger 104 is discharged through the discharge vents 242. [S309: AirDischarge Step].

The first retractable fan 200 may be rotated at a predetermined angle. Auser may input a user manipulation for the rotation of the firstretractable fan 200 through the input unit 17. If it is determined thatthe user operation for the rotation of the additional retractable fan200 is input through the input unit 17, the controller 600 controls theoperation of the first retractable fan 200 in the air managementapparatus. [S311: User Operation Input Step].

The control unit 600 may drive a rotary motor 226 that provides arotational force to the first retractable fan 200. [S313: Rotary MotorDrive Step]. The first retractable fan 200 may be rotated by therotation motor 226. As the first retractable fan 200 rotates, the airheat-exchanged in the heat exchanger 104 may be discharged to theoutside. [S315: Rotational Air Discharge Step].

FIG. 46 in conjunction with FIG. 42 illustrate an additional controlmethod of the air management apparatus for discharging the humidifiedair through at least one of the first retractable fan 200 or secondretractable fan 200′ with the heat exchanger 104 turned off. A user mayinput and set an operation for added humidity to the surrounding throughthe manipulation of the input unit 17. The user may directly touch theinput unit 17, or may input the user operation through wirelesscommunication with an external device. If user operation is determinedto be valid, the controller 600 starts the operation control forhumidification in the air management apparatus [S401: User OperationInput Step].

The controller 600 initiates the humidification process by raising atleast one of the first retractable fan 200 or the second retractable fan200′ to protrude above the upper surface of the housing 10. For example,the controller initiates the operation of the lift motor 230 installedin the first lift platform 214. The rotation of the second lift gear 232coupled to the shaft of the lift motor 230 and engaged with the firstlift gear 212 vertically raises the first lift platform 214. As aresult, the first retractable duct 234 coupled to the first support ring216 of the first lift platform vertically rises with the first liftplatform 214. [S403: Retractable Fan Rising Step].

Optionally, or in addition, the controller 600 may drive the firstprimary impeller 131 and may drive the second impeller 131′ and/or thirdimpeller 131″ to supply the indoor air to the inside through the bottominlet 11′. If the heat exchanger 104 is turned OFF, and thecorresponding louvers 141, 142, and/or 143 may be opened to allowdischarge of air [S405: Optional Primary Impeller and Louver OperationStep]. If the corresponding primary impeller or impellers is operated,air is sucked from the outside into the housing 10 through the bottominlet 11′ to flow into the main air flow passage 102. [S407: OptionalAir Intake Step]. Further, the controller may open the correspondingdampers to allow passage of air from the branch air flow passage 129 atleast one of the first retractable fan 200 or the second retractable fan200′. [S409: Optional Brach Flow Air Passage Step].

If the optional steps S405 to S409 is not desired based on the userinput in step S401, the process may go immediately from step S403 tostep S411. [S411: Humidity Generation Step]. The air from the main airflow passage pressurized by the inlet fan 403 and sent to the steamgenerator 407 through the air transfer duct 405. The humidification pump417 supplies water from the bucket 419 to the steam generator 407 undercontrol of the controller 600, and the steam generator 407 producessteam from the liquid transferred from the bucket 419. The generatedsteam is mixed with the air delivered through the transfer duct 405.

The humidified air may be delivered to at least one of the firstretractable duct 234 or the second retractable duct 234′ through atleast one of the first discharge duct 409 or the second discharge duct411 based on opening or closing of dampers. [S413: Humidity Delivery tothe Retractable Fan Step]. For example, when the humidified air isdischarged through the first retractable duct 234 on the left side ofthe housing 10, the damper for the first discharge duct 409 is openedfor connection or communication the first connection passage 205 of thefirst connection duct 204. The first damper 206 may be closed to cut offcommunication with between the branch air flow passage 219 and the firstconnection duct 204 to prevent mixing of air and humidified air causingformation of condensation or moisture in the first connection duct 204.

If a user selects rotation of the first retractable fan 200 through theinput unit 17, the controller 600 initiates the rotation of the firstretractable fan 200. [S415: User Operation Input]. As can beappreciated, such an input may be previously provided through step S401.Based on the rotary motor 226 being driven, the first retractable fan200 rotates to further disperse the humidified air. [S417: Rotation ofRetractable Fan Step].

FIG. 47 in conjunction with FIG. 42 illustrate an additional controlmethod of the air management apparatus for discharging the humidifiedair through at least one of the first retractable fan 200 or secondretractable fan 200′ with the heat exchanger 104 turned ON forsimultaneously performing the air temperature setting andhumidification.

The user may input a user operation for air temperature setting andhumidification through the input unit 17 formed on the front surface ofthe housing 10 of the air management device. The user may directly inputthe user operation by directly touching the input unit 17 or may inputthe user operation through wireless communication with an externaldevice. [S501: User Operation Input Step].

If it is determined that a valid user operation is input through theinput unit 17, the controller 600 may start the operation of the airmanagement device by starting the operation of at least one of theprimary impellers 131, 131′, 131″ to rotate at least one of the primaryimpeller blades 130, 130′ and 130″, respectively. [S503: Drive FanOperation Step]. When at least one of the primary impellers 131, 131′,131″ are operated, air surround the housing 10 is drawn through thebottom inlet 11′ and introduced into the main air flow passage 102.[S505: Air Suction Step]. When the air flows into the main air flowpassage 102 of the primary air flow space through the bottom inlet 11′,heat exchange proceeds in the heat exchanger 104 disposed inside thehousing 10. To this end, the controller 600 drives the heat exchanger104 to perform heat exchange. [S507: Heat Exchange Step].

The heat exchanged air of the heat exchanger 104 may be delivered to atleast one of the discharge ports 15′-1, 15′-2, 15′-3 provided on thefront plate 15 of the front plate 15 by the rotation of at least one ofthe primary impellers 130, 130′, 130″. The discharge ports 15′-1, 15′-2,and 15′-3 serve to discharge the heat exchanged air to the livable spacein which the housing 10 is located. [S509: Air Supply Step to DischargePort]. Because the louvers 141, 142, 143 determine opening and closingof the outlets 15′-1, 15′-2, 15′-3, the louvers 141, 142, 143 must beopened. [S511: Louver Opening Step].

The heat exchanged air as described above may be supplied to at leastone of the first retractable fan 200 or the second retractable fan 200′through the corresponding branch air flow passage. For example, if theuser input selected discharge of air through the first retractable fan200, the branch air flow passage 129 allows heat exchange air to flow tofirst connection passage 205 of the first connection duct 204 by openingthe first damper 206. [S513: Branch Air Flow Step].

The inlet fan 403 of the humidifier 400 draws in air from the main airflow passage 102 to deliver the air to the steam generator 407 throughthe air transfer duct 405. The steam generator 407 heats the liquiddelivered from the bucket 419 to generate steam, and the steam is thusmixed with the air delivered through the air transfer duct 405. [S515:Humidifying Air Generation Step].

At least one of the first retractable fan 200 or the second retractablefan 200′ may be raised to discharge humidified air or heat exchange airto the outside. For example, if the user selects on the firstretractable fan 200 in step S501, the controller initiates the operationof the lift motor 230 installed in the first lift platform 214. Therotation of the second lift gear 232 coupled to the shaft of the liftmotor 230 and engaged with the first lift gear 212 vertically raises thefirst lift platform 214. As a result, the first retractable duct 234coupled to the first support ring 216 vertically rises with the firstlift platform 214. [S517: Retractable Fan Rising Step].

The humidified air is supplied to at least one of the first retractablefan 200 or the second retractable fan 200′ through at least one thefirst discharge duct 409 or the second discharge duct 411. For example,if the user selection in Step S501 indicates discharge of heat exchangedair through the second retractable fan 200′ and discharge of humidifiedair to the first retractable fan 200, the first damper 206 may be closedwhile the first discharge duct 409 of the humidifier 400 is opened toallow passage of humified air to the first connection passage 205 suchthat the heat exchange air, especially cooled air, provided through thebranch air flow passage 129 may not mix with the humidified air to formcondensation of liquid in the first connection duct 204. [S519: Deliveryof Humidified Air to Selected Retractable Step].

If a user selects rotation of the first retractable fan 200 through theinput unit 17, the controller 600 initiates the rotation of the firstretractable fan 200. [S521: User Operation Input]. As can beappreciated, such an input may be previously provided through step S501.Based on the rotary motor 226 being driven, the first retractable fan200 rotates to further disperse the humidified air. [S523: Rotation ofRetractable Fan Step].

In the illustrated embodiment, three discharge ports 15′-1, 15′-2, and15′-3 are disclosed, but any number may be possible with different sizedopening. Further, there may be one-to-one correspondence between thenumber of discharge ports and number of louvers, variations arepossible, e.g., two discharge ports with a single louver to open orclose the discharge ports. Various configurations of discharge portopened/closed and first and second retractable fans protruding from theupper surface of the housing 10 are possible. For example, the louversmay be closed to deliver the heat exchange air only to at least one ofthe first retractable fan 200 or second retractable fan 200′ or air sentto the opened louvers and protruding retractable fan. In other words,due to the independent operation of the louvers and retractable fans,the configuration for discharging air may be independently controlled bythe user.

In the illustrated embodiment, the branch air flow passage 129 is incommunication with the first vertical duct 208 through the firstconnection duct 204. However, the branch air flow passage 129 and thevertical duct 208 may be directly connected with the first damper 206interposed therebetween. In the illustrated embodiment, in the positionof the first vertical duct 208 in the first inner frame 202 is biasedtoward the end of the housing 10 relatively away from the primary airflow space 20.
